In this article we will discuss about:- 1. Definition of Biofilters 2. Microbial Potential of Biofilters 3. Biofilter Media 4. Mechanism. Biofiltration is a new technology used to purify contaminated air evolved from volatile organic and inorganic compounds by involving microorganisms. It is a low cost technology gradually becoming popular due to simple operational and waste-removal efficiencies. Biofiltration is the [...]
Anaerobic digestion is accomplished in three stages, solubilisation, acidogenesis and methanogenesis. Stage # 1. Solubilisation: It is the initial stage when feed stock is solubilized by water and enzyme. The feed stock is dissolved in water to make slurry. The complex polymers are hydrolysed into organic acids alcohols by hydrolytic fermentative methanogenic bacteria which are mostly anaerobes (Fig. 33.3A). Stage [...]
In this article we will discuss about the biodeterioration of various materials. 1. Biodeterioration of Stored Plant Food Material: The stored (unprocessed) plant material (fruits, seeds, etc.) are usually decayed due to post harvest attack of bacteria and fungi. This kind of spoilage is called biodeterioration. However, loss of plant materials before harvest is covered in plant pathology. The microbes [...]
